I discovered that many people who live with another family for whatsoever reason do have clashes with their host at some point or the other, depending on how long their stay is. This ought not to be.
The fact that you are staying with your relative and his/her family does not give you the liberty to behave as you please; wake up when they do and others, does not call for clashes. Help in household chores when necessary. Avoid keeping late nights if the family is opposed to the idea. Go to church when they want you to go.
As a matter of fact, no matter how old you are, the key to living peaceably with a relative is to become a child of the home, not an authority.
More importantly, do not act like Lot who appeared ungrateful. He could not control his servants and was willing to exchange issues with his benefactor. Be like David who although lived with a difficult master; still tried everything in his power to please him. The fact that, Saul threw a spear at David did not make him act disrespectfully to Saul at any moment.
Hear his words; “The Lord forbid that I should do this thing to my master, the Lord’s anointed…” The next verse continues: “So, David restrained his servants with these words and did not allow them to rise against Saul…” (1 Sam. 24:6-7).
Knit yourself into that family deliberately and show respect and consideration. Have it in you that you should not remain in that position forever. Have a plan and let them know of the plan.
If you are going to be staying with them for a few days, weeks, months or years, appreciate them for the hospitality and inform them that within a specified period, you will move. Do not leave a bitter taste in their mouths when you go, rather let them be filled with sweet memories of your stay. Be useful and make the family happy. Do not be an ingrate. Again, do not be an authority. Be under authority. Love you!
